We used three different services to test if a Realistic Walk Cycle Animation can be created in PowerPoint 365 Live, Google Slides, or Office Live. Unfortunately, the Flash Once animation effect which is required to accomplish this kind of animation is missing from all three applications. So, we have to use the Appear/Disappear animation effect to get the results. The results were not as good as we get in the Desktop version of PowerPoint but still, you can learn a lot of new things with this tutorial.
